GR I N-TREATTNG MACHINE.

Specification of Letters Patent. Application filed May 13, 1913.

Patented Dec. 2, 1913. Serial No. 767,409.

An object of the present invention is to provide a machine which is adapted to grade and clean seeds and grain.

A further object is to provide a machine adapted to separate foul seeds and what are known as smut balls from the good l seeds. 7

A further object is to provide a machine which may be used as a fanning mill and in combination therewith a water containing tank, which water may contain a suitable disinfectant therein.

A further object is to provide a machine with a fan blower and a tank disposed therebeneath whereby the grain which drops upon the water within the tank is blown into a tank partially submerged and the heavier material will sink into a grain receiving tank disposed at the bottom of the main tank.

lVith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter clescribed and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the inven tion.

In the drawings accompanying this specification and forming a part thereof, the preferable form of my invention is illus trated, in which Figure 1 is a side view in elevation of my improved apparatus.

site side. Fig. 3 is a top plan view'with portions thereof broken away. Fig. 4 is a vertical cross sectional view taken upon a longitudinal axis of the apparatus.

Fig. 2 is a perspective view thereof looking from theoppow gated shelf 2 extending from what is termed Ethe back of the tank. The said tank and Eprojecting shelf is preferably formed of fwood provided with a liquid-tight metallic glining therein, though it is obvious that the tank may be made of other material pro :vided that a liquid-tight inclosure is obtained. Rigidly secured to the side walls of the tank 1 are the downwardly pro- :jecting legs 4 with suitable braces 5 extend jing therebetween and which supporting legs ;are adapted to retain the tank with the upper edge thereof disposed in a horizontal manner.

The front Wall 6 of the tank 1 is provided with an outstanding bracket- 7 the same exjtending around and secured to the side walls .as illustrated in Fig. 4. A receptacle 8 is positioned upon and supported by the out istanding bracket 7 and is termed a dirt re- ;ceiving receptacle, by which is meant that the said receptacle is adapted to collect and jretain therein the objectionable material {which always accompanies grain; smut jballs, wild oats, etc., being examples of what is termed objectionable material. The tank is adapted to receive water therein and with the level thereof slightly above the j upper extremity of the receptacle 8 so that ithe same will be entirely submerged and the material which is delivered upon the surface of the water will pass over the edges @of the said receptacle 8. A second recepftacle 9 is positioned upon the bottom of the tank 1 and is shaped soas to conform with the lower vertex of the triangular tank so as to always assume the same position with- ;in the tank. The receptacle 9 is termed a .grain receiving receptacle and is adapted to fcolleot therein the grain which upon being .delivered to the surface of the water, immediately sinks and as the same is delivered directly above the said grain receiving re- .ceptacle it will be collected therein, it being pointed out that the foreign material will be considerably lighter than the grain and will, by means of an air current, be

blown along the surface of the water above the dirt receiving receptacle 8 and will gradually collect within said receptacle. The dirt and grain receiving receptacles 8 and 9 are provided with a plurality of apertures or perforations extending therethrough, the same being small enough to prevent the grain or material which'has collected therein from passing through the said perforations when the receptacles are withdrawn from the tank and allowed to.

the grain which is "to be treated. Positioned drain.

The supporting legs t which are rigidly secured to the side walls of the tank stop. short of the upper edge thereof so that the supporting legs 10 of a superstructure may extend down partially over the said side The Walls and slidably engage the same. said superstructure comprises the top receptacle 11 which is ahopper and to the side walls of which are rigidly secured the said supporting legs 10. Rigid'ly secured to the supporting legs 10 and extending 'therebetween are "the beams 1'2 which are adapted to rest upon the upper edges of the side walls 3 to thereby support the entire superstructure and to mount the same slidable with respect to the tank. The supporting legs 10 of the superstructure extend down a short distance below the upper extremity of the side walls of the tank to thereby guide the said superstructure in its sliding movement, it being pointed out that the weight of the superstructure will hold the same upon the tank in a stable manner and that the friction exerted between the tank and superstructure will be sufficientto maintain the two in adjusted position. The hop-per 11 is provided with the downwardly slanting bottom walls 13 which are provided with a suitable opening 1 1 therebetween and in order to provide closing means for the same, the plate 15 is provided with a pair 'of rack bars 16 positioned upon and secured to the edges thereof and which bars are engaged and adapted to be actuated by the spurwheel ,pinions 17 which are mounted upon a suitable shaft provided with the handle 18 at one end thereof. From the foregoing it will be apparent that the outlet from the hopper 'may be regulated, the valve-like plate 15 sliding upon suitable guides 44.

of the sieve.

23, the same being detachably secured in Positioned directly beneath the hopper 111 hlch 18 secured t e p m1 3 is the screening sieve 18 theback portion of; which extends under the delivery outlet of the hopper and is adapted to receive the material as it passes therefrom. The back portion of the screening sieve is arcuated so as to accommodate the 'fan blower casing 19 which is also positioned directly beneath the rear portion'of the hopper. The screen'- 5 ing sieve 18 is supported at its rear portion by the links 20 and is pivotally secured adjacent its front end upon a crank shaft 21. which isrotatably secured to the sup-portpig le s 10. from which it wi 1 be a arent t lat! r y Wien the crank Shaft 21 is lgg a is open and is adapted to direct the draft screening sieve will be given an oscillatory. motion to thereby effect an eflicient screening of the material which passes over the screens The bottom plate 22 of the; sieve is provided with a detachable screen place so that one of a. number of screens may be used of dlfierent mesh according to directly beneath the screen 28 is an outlet spout 2-4, the same sloping downward and to one side and being provided with the open delivery end 25 so that the grain which passes through the screen 23 will be delivered from the end 25 of the spout beyond the side walls of the tank and into 'a suitable receiving receptacle which may be positioned therebeneath. The front end of the sieve 18" is open and a guide plate 26 is positioned therebeneat'h and angularly disposed with respect thereto whereby the material which passes beyond the screen 23 of the sieve falls upon the guide pl-ate'26 which is provided with a number of longitudinal corrugations or ridges whereby the material which is passed beyond the screen will be directed downwardly upon the surface of the water which is disposed within the tank. The longitudinal corrugations serve to check the velocity of "the material falling from the sieve and furthermore tend to lay the same gently down upon the surface of the water in a smooth manner and with the longitudinal axis of the material substantially parallel with the longitudinal axis of the tank.

Disposed within the cylindrical fan casing 19 is the fan wheel '27 which is rotatably secured to the supporting legs 10 and is provided with a pulley wheel 28 secured thereto and over which extends a belt 29 which in turn extends over and is driven by the manually-operable pulley wheel 30. The supporting shaft 31. upon which the fan wheel 27 is rotatably mounted is provided with the spur gear '32 rigidly secured thereto and meshing therewith is a second spur gear wheel 33, the latter having an arm 3i projecting eccentr'ically therefrom and to The ,pitman 35 is secured at its remote end to the crank shaft 21 and is adapted to rotate the same, from which it 'will be apparent that when the manually operable wheel 30 is rotated, the fan blower will be driven to thereby create an artificial draft of air and at the same time the crank shaft 21 will be actuated to thereby oscillate the sleeve 18. The fan wheel casing 19 is broken away adjacent the lower portion and extending 'approximately radial to the fan wheel and terminating central of the said casing opening is an air spout 36, the bottom of which opening. The arcuated plate 38 which acts as a slide valve for the air fan blower is provided with a rack bar 39 secured thereto,-

the same being illustrated in Fig. 1 of the drawings, and adapted to mesh therewith is a suit-able pinion gear 40 which'is rotatably supported upon a shaft provided with across the entire opening 37 of the fan casing. When the plate is in the posit-ion as illustrated in Fig. 4 of the drawings, it serves to regulate and to direct a current of air down upon the surface of the llquid i disposed within the tank 1, the velocity and amount of air directed thereon being proport-ionate to the opening of the said valve plate. The valve plate 38 may be also lowered so as to expose the under portions of the sieve to a blast of air as is the case in the ordinary fanning mill. The fan casing 19 is provided with the opening 42 at the upper portion thereof and which is provided with a hinged lid 43 for the closing thereof, the opening 42 being for the purpose of directing a draft of air down upon the sieve screen, this being necessary or de sirable in cleaning timothy and other grass seed, it being noted that either the rotation of the pulley wheel 30 will be reversed or the belt twisted so as to turn the fan wheel in a direction opposite to that in which it is turned when the lower opening 37 is used.

The grain which is to be treated will be placed in the hopper 11 and the said grain will contain such foreign material as smut balls, wild oats, foul seeds and stubble. The handle 18 will then be turned until the valve plate 15 which is supported upon the guides 44 as illustrated in Fig. 3 of the drawings, is withdrawn from the hopper opening which allows the said material to drop down into the/sieve 18. The driving wheel 30 is now rotated and the same will operate the fan blower and also impart an oscillatory movement to the said sieve. The material disposed thereon will be shaken and the same will either pass through the screen and out of the spout 24 or will drop upon the corrugated plate 26. Taking the case where wheat is to be cleaned, graded treated; the wheat is run over the screens of the .sieve which will be provided withho-les large enough to allow all of the wheat to...

pass therethro-ugh and to therefore be delivered from the outlet 25 of the spout and the wild oats and stubble will pass over the said screen and drop upon the corrugated plat-e down which it will slide to the top surface of the liquid disposed within the tank. The fan blower will produce a current of air which is deflected downward against the top surface of the water which will therefore blow the said stubble and material which has passed down the corrugated plate,

to the front end of the tank and over the dirt receiving receptacle 8 wherein it will gradually settle. A new screen is now positioned in the sieve coarse enough to grade the wheat when the same is again lntroduced nto the hopper and passed over the sa1d screen. The finer wheat will pass through thescreen and lnto the spout and the coarser grains along withisuch wlld oats as may be present with the wheat will fall upon the corrugated plate and will slide gently into the liquid; The draft of air produced by the fan blower drives the wild oats and stubble into the dirt receiving receptacle 8 while the large wheat kernels will immediately fSiIlk into the grain receiving receptacle 9. The grain receiving receptacle 9 is then withdrawn and positioned upon a grate 45 which extends across the rear portion of the tank and is allowed to remain thereon until :fthe water drains through the apertures with ,which the i said receptacle is provided. @Should it be so desired, a suitable disinfecitantmay be added to the liquid contained in the tank according to the grain being treated Eand the purpose for which the grain is to jbe subsequently used.

"When the machine is to be used as a fanin ing mill, the fan casing valve plate 38 will be rotated so as to close the air from 'the air spout 36 and will force the same Zbeneath the-screen sieve in the usual maniner. A fanning action will thereby be ob- ,tained and may be used during the treating ;of the grain.

'When it is desired to clean and grade itimothy, clover or other grass seed, the. bottom 22 of the sieve is removed and a screen iinsertedtherefor so that the seed will pass idown through the said screen and upon the top of the air spout 36 from which it may jbe removed and collected. In order to clean Ethe said seed, the valve slide plate 38 is placed in front of the opening 37 and the hinged flap or valve 43 is opened and the fan wheel reversed so that the current of air @will be forced out of the top of the fan fcasing and down upon the sieve and seed iwhich is passing thereover, it being noted that th tank is not filled with any liquid in this case. 7 q

From the foregoing it will be apparent thatwheat and barley and similar grain may be cleaned and graded, separated from smut balls, wild oats and stubble, and furthermore by the use of formaldehyde or other disinfectant the said grain can be cured and disinfected. The superstructure is slidably mounted upon the tank and may be removed therefrom if it should be so desired, in which instance the tank can be used for various other purposes. The superstructure is moved toward the front end of the tank when the grain receiving receptacle is to be drawn rearwardly therefrom.
